Both nations are currently undefeated this summer. Canada have defeated USA, Fiji and Tonga, while Ireland narrowly escaped Texas last week with an uncomfortably close 15-12 victory over the Americans.

Our Bleacher Report preview has called for a narrow Canada win, but the sand continues to shift beneath the feet of everyone on the shores of Lake Ontario.

Of the five Canadian players who emerged from their last match with injury concerns, only London Irish forward Jebb Sinclair has recovered sufficiently to take the field tonight against Ireland. Three Tongan players were suspended in the aftermath of that violent encounter last Saturday.

Meanwhile, Ireland have been dealing with an illness that made its way through their camp this week. Although no changes have been announced to their lineup, Ireland have been monitoring their players daily—a worrisome necessity with an already severely depleted squad.
